摘要
In this paper we consider the following Timoshenko system phi(tt) - (phi(x) + psi)(x) = 0, (0, 1) x (0, +infinity) psi(tt) - psi(xx) + integral(t)(0) g(t - tau)psi(xx)(tau)d tau + phi(x) + psi = 0, (0, 1) x (0, +infinity) with Dirichlet boundary conditions where g is a positive nonincreasing function. We establish an exponential and polynomial decay results with weaker conditions on g than those required in [F. Ammar-Khodja, A. Benabdallah, J. E. Munoz Rivera, R. Racke, Energy decay for Timoshenko systems of memory type, J. Differ. Equations, 194 ( 2003) 82-115]. (C) 2008 Elsevier Inc. All rights reserved.
